Cholesterol metabolism (WP632)

Rattus norvegicus

Cholesterol is essential for life - it's a required for the regulation of membrane fluidity. Cholesterol also serves as a precursor for many other biochemical pathways. Cholesterol is synthesized throughout the body but mainly in liver, intestines, adrenal glands and reproductive organs. Synthesis starts with the combination of Acetyl-CoA and Acetoacetyl-CoA. An important intemediary in the synthesis of cholesterol is mevalonate. Synthesis of cholesterol is regulated by a homeostatic mechanism.
